Kujala patellofemoral score.

Assessment will be done at each visit (pre-treatment, post-start treatment 3 weeks,, 6 weeks, 12 weeks, 6 months and 12 months) based on Kujala patellofemoral score. The Kujala score assesses following points: Limp, support, walking, stairs, squatting,running, jumping, prolong sitting with knee flexed,pain,swelling,abnormal painful kneecap movements, atrophy of thigh and flexion deficiency. Repeated measures linear regression models will be used to compare the two treatment arms with respect to knee function, pain score, and muscle strength from baseline to 12 months. Total duration of study is two years. We intend finish enrolling 92 patients by the end of one year after start of study. But each patient will be followed for total 12 months period. If any patient enrolled at 1 year mark after start of study , he will be followed for one year.

2 years. Total duration of study is two years. But each patient will be followed for total 12 months after enrollment. If any patient enrolled at 1 year mark after start of study , he will be followed for one year. So total duration of study is 2 years.

Visual analog pain scale (VAS) pain scale during activities of life

VAS scale of 1-10 will be used to evaluate knee pain. 1 being mild and 10 being worst.

Isometric strength measurement of knee

Isometric strength will be measured using dynamo-meter.

2 years

Secondary outcome measure would be how many return to sports activity.

Secondary outcome assessment will be to see how many in EMS+PT group and how many in PT group returned to their previous activity level of sports without any pain after completion of treatment.

2 years

At what point of time they returned to their sports activity

It will be also noted and compared between the groups at what time period after the start of treatment they returned to their regular sports activities. We hypothesize that EMS group might return early.
